ATTORNEY$ United States Patent Ofiice 2,738,578 Patented Mar. 20, 1956 SAFETY RAZOR Sauto Giambra, Jr., Pittston, Pa. Application July 6, 1953, Serial No. 366,219

1 Claim. (Cl. 393-4595) This invention relates to safety razors.

An object of this invention is to provide in a safety razor means whereby the blade may be adjusted so as to cut close or coarse as may be desired.

Another object of this invention is to provide an attachment for safety razors of the double edge type whereby the bade can be accurately adjusted with respect to the guard, the attachment including graduations whereby the same adjustment can be had with different blades.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claim.

In the drawing:

Figure 1 is a detailed front elevation of a safety razor partly broken away and in section constucted according to an embodiment of this invention.

Figure 2 is a detailed side elevation partly in section of the device.

Figure 3 is a fragmentary side elevation partly in section showing the blade holder in adjusted position.

Figure 4 is a sectional view taken on the line 4-4 of Figure 1.

Referring to the drawing, the numeral 10 designates generally a hollow handle having mounted on the outer end thereof a plate 11 and a pair of blade clamping jaws 12. Blade guard 13 is also carried by the plate 11 and a double edge razor blade 14 is adapted to be clamped between the clamping plates 12 and the guard 13.

A bar 15 is adapted to engage through the blade 14 and extends lengthwise through the meeting edges of the clamping members 12. The clamping members 12 are adjustable to a blade clamping or blade releasing position by means of a stem 16 which extends lengthwise through the handle 10. The stem 16 is endwise adjustable by means of a nut 17 which is threaded onto the outer end of the stem 16 and is swivelly carried as indicated at 18 by the handle or tubular member 10.

In order to provide a means whereby the blade 14 may be very finely adjusted toward or away from the guard 13, I have provided a cylindrical body 19 which engages about the nut 17 and is fixed relative thereto by fastening means 20. A pivoted nut locking member 23 carried by an elongated lever 24 is adapted to engage in a selected one in a series of circumferentially spaced apart notches 25 which are formed in the body 19. The lever 24 is pivoted on a pin 26 and lever 24 is constantly urged to locking position with respect to the locking member 23 by means of an elongated spring 27.

The safety razor embodying the handle 10 with the clamping members 12, the stem 16 and the nut 17 is a conventional Gillette safety razor holder. However, the holder hereinbefore described has no means whereby the user may finely adjust the razor blade on the head. With the attachment hereinbefore described embodying the body 19 and the tubular member 21 with the spring pressed locking member 23 the user may very finely adjust the position of the razor blade 14 with respect to the guard 13.

As shown in Figure 2, the outer or upper end of the lever 24 is provided with a projection 28 which is to be engaged by a thumb or finger so as to press the upper or outer end of the lever 24 inwardly and swing locking member 23 out of notch 25. The various notches 25 as shown in Figure 1 may be difierentiated by numerals or indicia 29.

In the use and operation of this attachment, the body 19 is secured on the nut 17 and the tubular body 21 is secured on the handle 10 by the set screw 22. Rotation in a counterclockwise direction of the body 19 and nut 17 will effect opening of the clamping jaws 12 so that a razor blade may be inserted on the bar 15. Rotation of nut 17 and body 19 in a clockwise direction will swing clamping members 12 inwardly toward each other and in an overlying position with respect to the blade 14. When the clamping members 12 are in a relatively tight position with respect to the blade 14 further rotation of the body 19 and nut 17 will pull stem 16 downwardly or inwardly and will also draw clamping members 12 downwardly or inwardly more tightly against the blade 14 so that blade 14 will, in proportion to the tightening of nut 17 and body 19 be moved closer to the guard 13.

The adjustment of blade 14 relative to the guard 13 is regulated by disposing the locking member 23 in selected one of the graduated notches 25.

What is claimed is:

In combination, a razor blade holder comprising a tubular handle, blade clamping means at one end of said handle, means extending through said handle including an adjusting nut at the rear of said handle for adjusting said clamping means, a tubular member embracing said handle, a set screw extending through said tubular member and engaging said handle to prevent relative rotation between said tubular member and said handle, a second tubular member mounted on said nut, key means connecting said second tubular member with said nut for relative rotation therewith, said second tubular member having a plurality of keeper notches formed therein, said first tubular member having an elongated longitudinally extending slot formed therein, an elongated locking member mounted on said first tubular member and disposed in said slot, said locking member having an end thereof adapted for selective engagement with one of said notches formed in said second tubular member, resilient means disposed in said slot and engaging against one end of said locking member and constantly biasing the other end of said elongated member into said selected notch, and indicia carried by said second tubular member adjacent said notches.
